修改
我有一个mysql表,其字段如下:
产品 - 序列号,名称,描述,价格,图片。
viewproducts.php页面如下:
<?php
$result = mysql_query("SELECT * FROM products ")
or die(mysql_error()); ;
if (mysql_num_rows($result) == 0) {
echo 'There Arent Any Products';
} else {
echo "<table border='0'><table border='1' width=100%><tr><th>Product Name</th><th>Description</th><th>Price</th><th>Image</th><th>Edit</th><th>Delete</th>";
while($info = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $info['name']. "</td>";
echo "<td>" . $info['description']. "</td>";
echo "<td>£" . $info['price']." </td>";
echo "<td>" . "<img src='../getImage.php?id=" . $info['serial'] ."'/></td>";
echo '<td> <a href="edit.php?product_id="' . $info['serial'] . '">Edit</a></td>';
}
}
echo "</tr>";
echo "</table>";
?>
我的edit.php页面如下所示:
<?php
$product_id = $_GET['serial'];
$result = mysql_query("SELECT * FROM products WHERE serial = '$product_id'")
or die(mysql_error()); ;
if (mysql_num_rows($result) == 0) {
echo 'There Arent Any Products';
} else {
echo "<table border='0'><table border='1' width=100%><tr><th>Product Name</th><th>Description</th><th>Price</th><th>Image</th><th>Edit</th><th>Delete</th>";
while($info = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $info['name']. "</td>";
echo "<td>" . $info['description']. "</td>";
echo "<td>£" . $info['price']." </td>";
echo "<td>" . "<img src='../getImage.php?id=" . $info['serial'] ."'/></td>";
}
}
echo "</tr>";
echo "</table>";
?>
当我从thr viewproducts.php页面点击编辑时,它会转到edit.php页面,其中没有任何内容显示。地址栏上的序列ID如下:
http://www.********.com/****/admin/edit.php?product_id=
我希望能够编辑从viewproduct.php页面点击的任何产品并转移到edit.php页面。我不认为我的edit.php页面是正确设置的。
请帮忙,

您可以通过$_GET
传递产品的ID,然后在编辑/删除页面中检索该参数。显然,在使用之前,您必须正确清理输入。例如,每个产品的链接应如下所示:
echo '<td><a href="edit.php?id="' . $info['id'] . '">Edit</a></td>';
在编辑页面中,你应该有:
$id = $_GET['id'];
// For example, if the product id is an integer
// you can sanitize it doing this
$id = (int) $id

你可以将它作为参数传递给你想要编辑/删除产品的php文件:
<a href="edit.php?product_id=<?php echo $row['product_id']; ?>">Edit Product</a>
然后在edit.php
中,您将获取产品的ID并从数据库中加载数据。
[edit.php]
$product_id = isset($_GET['product_id']) ? intval($_GET['product_id']) : null;
if(!$product_id) {
exit();
}
// query your database for the product
$row = mysqli_query("SELECT * FROM <table> WHERE product_id = $product_id");
// then you output your html with fields populated from the result from the database
